FlatList

FlatList is a high-performance React Native component for rendering scrollable lists of data. It efficiently handles large datasets by only rendering items currently visible on the screen, using a technique called virtualization. It supports features like pull-to-refresh, infinite scrolling, and customizable item separators.

Also known as: Flat List, React Native FlatList, RN FlatList, Flatlist, FlatList Component

Why learn FlatList?

Developers should use FlatList when building mobile apps with React Native that require displaying long lists of data, such as social media feeds, product catalogs, or chat histories. It is essential for optimizing performance in list-heavy applications, as it minimizes memory usage and improves scroll smoothness compared to basic ScrollView components.
